To all whom 'it may concern.'

Be it known that l, Quintana C. S'rn'rz, a citizen oF the United tatcs, residing' at Pittsburg, in the county of Allegheny and '5 Stato of ,lennbylvanim have invented new and useful lniproveniente` in Structures i'or Buildings, of which the following is a :speciication.

This invention relates to structures for buildings and consiets in certain improve- 'nnants therein as 'Will be hereinafter fully described and, pointed out in the claims.

More particularly the structlnfc for build ings is adapted to the construction of building walls formed of concrete iron and somo other plaaiic material. In the broader features oi' the invention some of these elements 'may be omitted but in the preferred construction it consists of I beams, concrete platea and locking devices for locking the plates with` the beams as well. as Supplying means by which the expansion of the parte inay be provided for.

The invention is illustrated in the accompanying drawinge follows z- Figuije l shows a cross section oi the structure. Fig. 2, a cross section Vof a structure in which the Wall is formed-ot' double plates.

Fin. 3, a 'fragment of a r'fle elevation of a 3o Walll.

A marks the I beam which is utilized in the preferred construction; B, the exterior wall plaie, and B', the interior Wall plate. ln some instances but a single wall plate is used and Where this is done, it is doubly reinforced 'at b and b2, but where the double Wall late is used only the inner pants of the p ato are reinforced as at o* and Z1". The edges of the plates have a locking con-- 4o tour. As Shown this locking contour con slots of a groove b into which is shaped the locking block C preferably formed oi grhut or concrete. ln the puttingv n i of the wall tho plate is ut in position and the grunt oi' concrete in t 1e plastic condition put in posi tion with relation to the plate. As this groin'.- or concrete hardens the plate l or B is securely locked with reltiointo the beam.

I prefer that the plates have an overlapping 5U edge and between the edges of the adja cent plates B there is placed a resilient cenient E which fills the s pace but still permite of expansion and contraction of the plates.

A similar expansion block E is arranged between the interior plates. l also prefer lo provide an elahlic veulent expansion piece l) between the locking' piece C andthe wel oi: the I licanluo an lo permit oi' Home lalilnde in this pa l'ticnlai' as well.

- The cement used for the expanaion blocks E and lil may be of any desired composition so long it is resilient. For ordinary slating cement, many of the cemcnts formed from coal tar asphaltum will answer the purpose. As shown in the drawingsl there are openings for expansion of the parts so that the liloekel C are in engagement with the I beams. As the I beams and cement plates contract, these resilient blocks expand Sulliciently to keep in contact.

What I claim as newA is 1. A Wall comprising a plate of concrete; and means for locking the plate in place, said means including a locking ieee, the plate and locking piece being provided .with corresponding protulot-rancesv and `indentures, the protuberances projecting into the indentures, and an elastic cement acting on the locking piece to permit of expansion and contraction of the plate, and to hold Vthe locking piece in engagement with the plate as the plate contracts.

2. A wall com rising a, concrete plate, `the edge of which flanged I beam; a locking piece engaging the inner faces of the flanges of the I beam and moldied to the shape of the edge of the` plate and en place relative y' to thoI beam; and an elastic cement between the beam and the locking piece to permit expansion and contraction.

3; A wall comprising an I bcam'; a con-V crete plate, having a part of itsfbo'ily overlapping and in contact with the edge of the I beam, the edge of the late being' along the face of the I beam, an said platehaving' au offset extending from said overlapping portion in the direction of the-beam, anda separate means engaging the lla-n?I of the I hmm and said` otf setvfor locking platefl place. p

4. A wall comprising an` I beam a c0ncrete plaie having part of itsrbodfy overlapping and in contact with the edge of the I beam, the edge of the plate being alon the face of the edge ofthe I beam, and sai" plate having Aan oil set cxtendingfrom `said overlapping portion in the direction of iheI beam and a concrete block eng,l ing the flange ol*l the I beamfand'aid" b ocl and as a locking contour; a.

ging the saine to lock it in off set having protuberances and corresponding indcntures interlocking for holding the plate in place on the I beam.

5. A wall comprisin an I beam; a concrete plate, having the ap ing portion. b* overlapping, and in conta Wit the odge of the I beam, and having a projection from the overlapping portion in which there is an under cnt c, and a cement block C engaging the flan e of the I beam, and extending into the nn er cnt portion c* for securing the plate to the I beam.

6. A Wall comprising a beam; a plate hav ing an overla ping portion bf* and an inwardly exten ing odset from said overlapping portion, said offset having a locking contour; a cement locking piece in engagement with said offset and the beam; and an elastic material between the locking piece and the beam for permitting expansion and contraction.

7. A wall comprising an I beam; cement plates arranged at both faces of the I beam; said plates facing each other, and forming a double wall and a cement lockingipieee forming a double wall, a locking piece CA formed of elastic material and molded to the shape of the undercut portion 0 and extending between the flanges on the I beam for locking the plates relatively to the I' beam.

In testimony whereof I have hereunto set my band in the presence of two subscribing witnesses.
